Sharing a picture from a past relationship

My husband and I have been married for 3 yrs. Like every normal relationship we had ups and downs in our past. We really enjoy sharing great pics on social networks. This time he shared a pic in particular that pissed me off. It's a pic of him when he went on vacation with an ex. The ex wasn't in the picture but the fact it was a place where we also vacationed a couple of yrs later that bothers me. He shared the memory of the time he went with her. This ex of his was a big problem and very negative towards our relationship. I don't believe that my husband should be sharing any memories from his past. It makes me feel like I'm being disrespected as his wife. Any thoughts or am I overreacting??? Help please!!

Felisha, Funny thing about men is, they don't seen to place much emotional importance on stuff like photos. If he chose a pic for FB, it's probably because it was one he looked good in! If there are no real problems ongoing in the marriage , there's probably nothing to worry about . You might compliment him on how good he looks and ask him to share a couple from your own vacation too !
